I live on a farm & always wondered if I should rotate wormer on dogs . We use ivermectin, Strongid, panacur & quest for my horses & goats. In fact I rotate my flea protection on dogs &. Cats. I will have to ask my vet his opinion on this .
I too have a rescue that had HW treatment over 7yrs ago. We use Iveheart Max year round. I know a lot of friends that are happy with the multi. I may try as fleas, mosquitoes & ticks are horrible! Frontline plus quit working for me & advantix isn't doing great with fleas for me right now.
Good luck

Lots of variables here -- the important think is to keep the dog on something to protect against heartworms!

I completely agree!

I, honestly, don't know if that is a factor in the HW drug-resistance that has been documented with dogs. But, it is interesting to hear that changing up de-wormers is a common practice when it comes to de-worming horses.

It seems to me that a lot of the current focus on the resistance issue is on the use of the "slow-kill" method to treat heartworm and on factors unique to the Mississippi Delta region due to studies that suggest that the "resistant" strain has not spread in ways scientists would expect based on other vector-borne diseases.

In non-MDR1 dogs, there's probably nothing more studied than ivermectin (the active ingredient in Heartguard, Tri-Heart, Iverheart, Pet Trust, etc.). It's been around forever, and the amount used in HW meds is super-low (it gets used (safely) in WAY higher doses to treat mange, for example). That said, I don't use it any more because of the resistance issues in my region. Until I became concerned about this, I used ivermectin-based products because of the long, long history of safety.

We've put Multi on many, many dogs in rescue, and I know lots of people who use it on personal dogs. I know of no adverse reactions -- it doesn't mean they don't happen; I just haven't heard of any. The biggest risk to it is consumer application error (putting it on the hair instead of the skin, and the dog not getting enough of the medicine).

The only major down side is the smell and not being able to pet the dog on the back for a few days (which can be annoying). That said, I'm in an area where year-round flea prevention is useful.

I also know lots and lots of people who use Trifexis without adverse reactions. Many find it far more convenient to just give a pill.

I think Riley's right--figure out what components you need year round, whether you need dewormer and if so what kind, and go from there to pick a suitable product. They're all approved by the FDA.

I also am finding more and more people using the 6-month Proheart 6 injection (the dog gets a shot every six months, no monthly doses to remember), if all you want is heartworm protection. My vet has his personal dogs on Proheart 6, in fact.

There's a ton of choices. It just all depends on your lifestyle and environmental needs, and what delivery method you find convenient.

Moxidectin is an FDA-approved heartworm preventive for dogs – it is the active ingredient in Advantage Multi for heartworm prevention. As Magwart stated, it is in the same product class as Ivermectin. A lot of studies have been done on the safety of moxidectin. According to the studies I have read, Moxidectin is both safe and effective. In fact, it seems to be safer than ivermectin for dogs with the MDR1 gene mutation (primarily collies).

The question I would ask myself, if I were you, is whether or not you need the "Multi" side of "Advantage Multi" year-round given where you live. For example, are fleas a year round problem where you live?

I would also consider what application/delivery method you prefer. The comments I made earlier about the topical application method were based on my personal preference, not safety issues.

Anyway, I hope Magwart re-visits this thread to share more of her personal experiences with using Advantage Multi.

Magwart –I didn’t find any scientific data to support (or refute) what I have been told by my vets re: using an ivermectin-based preventive for dogs that have previously been treated for heartworm…. it is very possible that this information is simply not up-to-speed on the latest thinking because I did get the distinct impression that my vet doesn’t see dogs that have been treated for being HW+ that often.

To be fair to my vet, I probably also dismissed Advantage Multi as an option for me as I really do dislike the topical application method and I do not live in an area where year round flea/tick treatment is necessary.

Anyway, I did find some interesting info on ML resistance that I thought I would post here for you. You have probably already read these, but just in case…

Do you by chance have any links regarding that recommendation? I'm curious what the documentation is on it. I know a lot of treated dogs who are currently on Trifexis and Multi (neither is ivermectin-based).

Advantage Multi uses moxidectin, which is the same class as ivermectin, but formulated differently. Down here, many vets actually are putting HW+ dogs on Multi instead of ivermectin-based products. Our rescue's vet wants all the HW+ dogs on Multi, not ivermectin.

Hi Magwart,

That is really interesting to hear. I will see if I can find some info, but primarily this is what I have heard from veterinarians in my area. I know that my vet special orders HeartGuard for me because the product they sell is not Ivermectin-based and they recommended that I use an Ivermectin-based product.

It seems that I may have some more research to do on this topic as I bet the vets in your area have a lot more experience dealing with dogs that have been treated for HW than my vet.
